PRG/211 Week 1

Individual: University Project: Problem Solving with Algorithms

Includes Working Visual Logic Flowchart!

Also includes Steps (Algorithm), Pseudocode, and Visual Logic flowchart file!

During this course you will design a program for a state university. The university needs a website design that will enable students to order books online. Each week you will receive additional instructions for the elements of the design based on the needs of the university. The elements will correspond with the concepts and skills you learn that week.
According to the university's website design request, students need to order five books, one for each of the five required courses that all students take. You need to design a program that will prompt students for the price of each book and display the total cost for the five books.

Create a 1- to 1 3/4-page document listing the steps needed to solve the problem using an algorithm, including the following:
    • Identify the input needed
    • Define what the input must do (i.e., the process)
    • Show what the output must produce
Create a 1/2- to 1-page document of your pseudocode based on the algorithm, including the following:
    • Write the pseudocode statement(s) for the input
    • Write the pseudocode statement(s) for the process
    • Write the pseudocode statement(s) for the output
Create a 1-page flowchart based on the algorithm, including the following:
    • Mark the program's starting point
    • Represent the input steps in the program
    • Represent the process steps in the program
    • Represent the output steps in the program
    • Mark the program's ending point

Write the Algorithm, Pseudocode, Flowchart, and Python code for the following programming problem. Team Average  A college wants you to write a program for them that will calculate the average number of wins for their football team over the past five years.  The user of the program should be able to enter the number of wins each year.  The program will calculate the average number of wins during that five year period and display that information to the screen. 

NOTE: Discussion Questions are different depending on which Instructor you have, however the following questions have been included as a BONUS for this tutorial.

Discussion Question: Algorithms

Consider a potential business problem that would require a computer program solution. Discuss how an algorithm might be used to solve a problem that a business may encounter.

Supporting Activity: Additional Discussion Questions

1.  Why is a flowchart useful in developing and documenting software?

2.  Why is the interactive Visual Logic flowchart program more useful than a

      manually drawn flowchart?

3.  Is a flowchart more valuable in documenting the logic of a program than just

      the coded instructions in the programming language? Explain your answer.

4.  What are the similarities and differences between procedures and objects?

5.  What is an example of software that would be best implemented in procedural

      programming?

6.  What is an example of software that would be best implemented in object-

      oriented programming?

        options: delivery or pick-up
    • Use an if statement to add the charges to the total price if the shipping  

        charges are greater than 0
    • Display the total cost
Create a 1/2- to 1-page document containing pseudocode based on the revised program needs. Add this to the revised program pseudocode from the Week One Individual Assignment, Problem Solving with Algorithms.
